Hi…
I’m having 404 issues as well after the 3.1 update (note to self, DO NOT UPGRADE UNTIL ALL IMPORTANT PLUG-INS ISSUE UPDATES AS WELL)…
All my permalinks don’t work anymore ( ‘/%category%/%postname%/’ ) but works fine when reverted to the ?=123 default.
I’m using Dean’s Permalink Migration and it couldn’t redirect the default permalink structure to the custom permalink anymore.
My site relies on a lot of incoming links from forums and other organic sources so if their hyperlinks (using the ‘/%category%/%postname%/’ format) doesn’t work, my site wouldn’t get much traffic.
My site has been working fine for 2+ years, and now it’s down due to this update grr.
Please help if you can. I’ve tried creating a new htaccess after disabling all plug-ins, no luck. The only time it’ll work is when I reverted the permalink to the default.
My site is https://reviews.davidleetong.com thank you
